New Zealand GoogleEarth KML File

Hi everyone,

This is a technical post.   It follows posts on a set of New Zealand OpenCPN waypoints and another on an associated set of KAP 'charts'.  Here we put the waypoints in GoogleEarth itself, providing another means of visualising the places and their surroundings.

Overview

Here are links to the preceding posts:

• New Zealand Anchorages
• New Zealand GoogleEarth KAP Charts

Here are links to the three folders holding this data on our Dropbox site:

• GPXlibrary
• KAPlibrary
• KMLlibrary

None of this information is for use in navigation!

To use GoogleEarth you can either install the Google Earth Pro app or run Google Earth in your browser.  In either you can load our KMZ file.  Then you can explore the ~400 anchorages, moorings and marinas in our set.

The waypoints are shown using two icons, each in two colours:

  Anchor:  Green => swing or rig own shore line(s); and Red => shore line(s) provided.

  Marina/Mooring:  Green => marina; and Red => mooring or moor to hawser.

The need for shore lines is described in the text associated with each waypoint.  This text is identical to that in the GPX file.

The screenshots below show the waypoints in various popular cruising areas.

Hauraki Gulf

Abel Tasman and Marlborough Sound

Fiordland

Stewart Island

The GoogleEarth Tour below gives an idea of the detail available, moving from Three Kings Islands in the north to Stewart Island's Port Pegasus in the south via Opua, Auckland, Nelson, Milford Sound and Preservation Inlet.

New Zealand GoogleEarth KAP Charts

Hi everyone,

This is another technical post.  Last week I created a set of about 400 New Zealand anchorage, mooring and marina waypoints, primarily for use in OpenCPN.  They're publicly available and described here.  This week's task was to create GoogleEarth KAP satellite image 'charts' for them all.  KAP charts can be displayed in OpenCPN.

Viewing Zen Again's location in OpenCPN using KAP charts

Many sailors using satellite imagery in OpenCPN have abandoned KAP charts in favour of MBTILES charts.  The latter allow one to zoom in and out, viewing varying levels of detail while doing so.  I prefer to only use satellite imagery when zoomed in on a small area, for example a narrow pass or a small bay.  KAP files are also much smaller, for example MBTILES for all New Zealand is about 6GB while my KAP files are about 400MB.  Both formats have their uses.

Read this post to learn about our KAP library and how to use satellite imagery.

The KAP library is on Dropbox here and the new file is NewZealand.zip.

The quality of satellite imagery varies enormously - regardless of format.  Below are a series of KAP charts in OpenCPN.  They range from very clear to 'clear as mud'.  Many of the Fiordland images are very dark due to poor light in the fiords - they're surrounded by tall mountains after all!

Harrison Cove in Fiordland

If you look carefully at the image below you'll see lots of small red 'dots'.  They're actually rectangles showing the location of each chart.  The set includes all main cruising areas, but of course no set is exhaustive.

All of these KAP charts were created using the VFKaps OpenCPN plugin.  This fantastic tool makes the process very easy.  The 'VF" in VFKaps refers to VentureFarther, a web site setup to assist cruisers.  To create KAP files using the plugin you need to pay a US$20 subscription to VentureFarther.  This buys you the API key required by the plugin.  Worth every cent!

New Zealand Anchorages

Hi everyone,

This is a technical post!  It describes a GPX file downloadable from our public Dropbox site.  The file contains about 400 New Zealand anchorages, moorings and marinas.  I expect it to grow over time.  It has been compiled primarily from cruising guides.

Overview

The accuracy of these waypoints has NOT been verified. 

NOT for use in navigation.

GPX files can be loaded into many chartplotters.  This file was constructed in OpenCPN v5.  We have not tried other chartplotters and welcome feedback advising success/failure.

Four main symbols are used:

 Swing anchorage or anchor and rig own shore line(s)

 Anchor and use provided shore line(s)

 Swing mooring or side-moor hawser

 Marina

The GPX file may be downloaded from our Dropbox GPXlibrary folder here.

The filename is 'ZenAgain_NZ_Waypoints.gpx'.

Other files in this folder are zip files of our tracks in various parts of the world.

Most of the marks/waypoints have the ScaleMin parameter set.  This prevents densely packed waypoints obscuring the under-lying chart.  Only those in the screenshot above don't.  For example here is a screenshot showing Northlands overall, including the Bay of Islands.  Only a few are visible in the Bay of Islands.

Northlands Overview

And here's the full set in the Bay of Islands.  They emerge as you zoom in.

Another example is Fiordland where only one is visible in the top screenshot above.  Zoom in to see them all.  The screenshot below shows most but not all.

And finally here's a screenshot of Port Pegasus, Stewart Island.

Sources include:

• Boaties Guide to Fiordland (BG2F)
• Coastal Cruising Handbook (CCH)
• Fiordland by Sea (FbS)
• Northland Coast Boaties Atlas (NCBA)
• Stewart Island Cruising Guide (SICG)
• Island Cruising South Island Rally yearbook (SIR)
• NoForeignLand

Some of the marks/waypoints provide a NoForeignLand URL and/or cruising guide pages using the acronym shown in () above.  Here's an example's Properties in OpenCPN.  It has three separate sources and ScaleMin is enabled and set to 2000000.

 

All names (but not the example above) start with 'ZA_'.  This allows easy sorting and deletion.

The file will be updated occasionally as our New Zealand cruise progresses.

Here's hoping cruisers will find the file useful.  If you do feel free to buy us a beer - link at top-level!
